CVE-2026-89915 KVM: arm64: Remove VM-wide VNCR mapping counter

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Remove VM-wide VNCR mapping counter The global VNCR mapping counter is used to decide whether an L1 provided VNCR page is mapped in L0 on any CPU at the point of dealing with a TLB invalidation. It is incremented when...

CVE-2026-89916

CVE-2026-89916 is a race condition in the Linux kernel's KVM arm64 subsystem where VNCR TLB invalidation did not participate in the MMU invalidation retry mechanism. When one vCPU invalidates a page via TLBI S1E2 while another vCPU is concurrently faulting in the same page, the faulting vCPU can ...

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Make VNCR invalidation participate in MMU invalidation retry A VNCR TLB invalidation can occur on one vcpu while another vcpu is faulting in this same page. Without correctly handling this, we can end up with the...

CVE-2026-89915

This vulnerability affects the Linux kernel's KVM arm64 subsystem, where a flawed VM-wide VNCR mapping counter is used to decide whether an L1-provided VNCR page is mapped in L0 during TLB invalidation. The counter can result in missed TLB invalidations , and fails when an L1 vCPU invalidates its...

CVE-2026-89911

CVE-2026-89911 affects the KVM arm64 subsystem of the Linux kernel. The root cause is an integer overflow in the handling of TLB Invalidation by Range (TLBI) : because the TLBI range can be encoded with a large value based on an arbitrary virtual address, a guest can trigger an overflow if the hy...

CVE-2026-89911 KVM: arm64: Correctly cap TLBI Range to the architural limit

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Correctly cap TLBI Range to the architural limit TLB Invalidation by Range has a fairly powerful way of encoding pretty large ranges in a small number of bits. This range can be based on an arbitrary VA, which means i...
